adapted to the individual needs of a patient. All dosage indications are mean values which may vary
according to skin condition and sensitivity.

Depending on the photosensitivity of the patient and the clinical picture, the treatment dose can be
individually further increased accordingly.
Due to individual skin sensitivity, itching / skin irritation may occur following initial treatment. Patients
should be informed of this prior to the commencement of therapy. Should itching / irritation occur,
doses should not be increased for several days until these complaints have subsided.
Emollient treatment of the skin is recommended after every phototherapy treatment.
